LTQ XL™ Linear Ion Trap Mass Spectrometer

 Related applications:
Industrial Mass Spectrometry

Obtain high sensitivity full scan MS along with in-depth MSn (CRM) capabilities with the Thermo Scientific™ LTQ XL™ linear ion trap mass spectrometer. A single quadrupole offers Selected Ion Monitoring. A triple quadrupole adds Selected Reaction Monitoring. A linear ion trap goes further by enabling Consecutive Reaction Monitoring where a selected ion is fragmented into a product ion and the resulting product ion further fragmented in additional consecutive steps. Each additional fragmentation step makes compound identification more certain and facilitates structural characterization.

Description

The LTQ XL ion trap MS extends the legendary MSn performance of the LTQ ion trap, incorporating more techniques to generate structural information through innovations in Thermo Scientific ion trap technology.

  • Unparalleled sensitivity and unmatched MSn spectral quality
  • Pulsed Q dissociation (PQD) for generating more fragments and extending the low mass range
  • Electron transfer dissociation (ETD) option provides sequence information not available from conventional methods
  • High-resolution isolation (HRI) enables isolation of isobaric mass peaks for cleaner MSn spectra
  • Ultra-fast polarity switching for high sensitivity analysis of unknowns
  • Automated data-dependent neutral loss for PTM and biotransformation analyses
  • Excellent charge state determinations with Ultra ZoomScan™
  • Upgradeable to Thermo Scientific™ LTQ Orbitrap XL high-resolution, accurate-mass technology

The LTQ XL supplies outstanding sensitivity and abundant structural information for:

  • Protein identification and quantitative differential expression analysis
  • Biomarker studies and PTM identification
  • Metabolite identification and quantification
  • Tissue imaging
  • High-speed LC methods
For Research Use Only. Not for use in diagnostic procedures.
